It is grilled into 38, roller to be gathered in after the sheet material processed on pallet carries out post processing and transfer towards storehouse pallet 40 side.This Shi Bixu makes the direction of rotation being grilled into roller 38 rotate in the opposite direction, for that purpose it is necessary to make exit roller 31b towards in opposite direction with ADF Direction rotate.
Here, by being separately provided the rotation drive motor of exit roller 31b and being grilled into the driving motor M3 of roller 38, it is possible to By be grilled into roller 38 carry out the sheet material after post processing from process pallet 35 send ADF action time with exit roller 31b follow-up Sheet material passes out to process pallet from ejection port 29a.
(kicking to send mechanism)
Between ejection port 29a and twist rollers 36, need from the Web guide of ejection port 29a to the position of twist rollers Guiding mechanism, and be used for sheet material rear end to be directed to be grilled into the guiding mechanism of roller 38 from ejection port 29a.
Especially, have in the paper-discharge mechanism of big ladder, when sheet material rear end falls between ejection port 29a and process pallet 35 Under to when processing on pallet, hang over the sheet material on the side face of exit roller 31 and may cause paperboard.
Here, the device of diagram is configured with between ejection port 29a and twist rollers 36 and is kicked to send mechanism by what following structure was constituted. Fig. 4 represents that it constructs in detail.
To kicking to send before mechanism illustrates, the action to passing out to process the sheet material on pallet from ejection port 29a is entered Row explanation.
The sheet material front end that ejection port 29a sends from exit roller to 31a, 31b by carrying capacity towards processing turning over pallet The operating position Ap(of transfer roller 36 now twist rollers 36 is position of readiness Wp so being engaging precalculated position) conveying.
Then, when this sheet material front end is by operating position Ap, twist rollers 36 declines, and gives carrying capacity to sheet material.This state 31a, 31b are clamped with twist rollers 36 by exit roller and are endowed carrying capacity by lower sheet material respectively.And when sheet material rear end is by row During paper mouth 29a, this sheet material rear end is fallen and is processed loading above sheet material on pallet.
After sheet material rear end is fallen on process pallet, under the reverse rotation (back coupling) of twist rollers 36 acts on, entrance is grilled into roller 38, collide with position limitation retainer 37 under the conveying effect of two rollers and limited.
In such paper-discharge mechanism, it may occur that sheet material rear end hangs over and produces paperboard, sheet material on the side face of exit roller 31 Rear end is flexed and is grilled into roller 38 and clamps and cause the unfavorable condition of the rear end bending of sheet material.
Meanwhile when in view of sheet material rear end by being affected from outside wind etc., sheet material slow falling motion ground Assemble, make collection efficiency significantly reduce.
In order to solve these unfavorable conditions, the present invention arranges playing of following mechanism between ejection port 29a and twist rollers 36 Send mechanism 50.
This kicks to send mechanism as shown in Figure 4, can configure by swing arm parts 50 in the way of rotating on device framework Constitute kicks to send parts.
It is referred to as swing arm parts below when concrete structure is illustrated, referred to as kicks to send when its entirety is indicated Parts.These swing arm parts 50 are the action appearance of standby attitude Fa up and lower section in the way of intersecting with ADF path line PL Reciprocally constitute between state Fc.
On device framework, the radicle 50x of swing arm parts 50 can swingingly be supported in axle branch 36x, and axle props up Portion 36x by the sleeve 51 that is rotatably assorted so that the axle branch of the arm member 41 with above-mentioned twist rollers 36 can be supported on by the way of swinging On the axle that 36x is general.This is to make device simplicity, it is also possible to be supported on the fulcrum different from the support shaft of twist rollers 36 On.
These swing arm parts 50 form front end arm 50a and rear end arm 50b across axle branch 36x.It is configured to, Enable front end arm 50a at the standby attitude Fa(Fig. 4 solid line kept out of the way upward of ADF path line PL) and pass through ADF The engaging attitude Fb(Fig. 4 chain-dotted line engaged above of the sheet material of path line PL) and it is in the process below ADF path line Movement posture Fc(Fig. 4 dotted line on pallet) between swing.
As shown in Figure 4 (b), it is formed with the 1st spigot surface (the 1st guiding parts) Ga and the 2nd spigot surface at front end arm 50a (the 2nd guiding parts) Gb.
1st spigot surface Ga is when front end arm member 50a is in standby attitude Fa, sheet material from ejection port 29a towards upset The operating position Ap of roller 36 guides along ADF path line PL.
And, the 2nd spigot surface Gb when front end arm member 50a is in the movement posture Fc processed on pallet sheet Material is directed to be grilled into roller 38.
It addition, the 1st the 2nd above-mentioned spigot surface Ga, Gb is configured to, relative to guiding length (Fig. 4 of the 1st spigot surface Ga) longer (the Ga ＜ Gb) that the guiding length (Fig. 4 Gb) of the 2nd spigot surface is set.
This is because, be directed into the sheet material of twist rollers 36 from ejection port 29a, as long as its front end towards the upset in downstream The direction of roller (correct for operating position Ap) guides, and is therefore set to that comparatively short guiding length is (meanwhile, by this is led Can be with miniaturization of the apparatus to the short of length setting).
To this, the 2nd spigot surface Gb must be positioned at process the sheet material feeding bent in the form of a ring on pallet in taking off of downstream Enter roller 38.
Finally, when being feedback towards the direction of position limitation retainer 37 by 36 sheet materials of twist rollers, sometimes after sheet material End can not be nipped and is grilled into roller 38 and cannot accept carrying capacity from this roller.Now, it may occur that sheet material rear end is being grilled into the face of roller 38 Before (twist rollers side) looped-shaped bending, and when front end warpage enter be grilled into the such unfavorable condition of roller 38.
Here, by the 2nd spigot surface Gb is set to longer than the 1st spigot surface Ga, it is possible to by the 2nd spigot surface Gb to sheet material after End is deformed into big ring-type situation and is any limitation as, and makes sheet material rear end enter swimmingly and is grilled into below roller 38.
And, front end arm 50a is displaced to from standby attitude Fa of top in the way of intersecting with ADF path line PL The movement posture Fc of side.Now the 1st spigot surface Ga1 make forcibly from ejection port 29a departing from the rear end of sheet material fall accumulation On the sheet material processed on pallet.
Possessed to this end, kick to send parts 50 and passed through ejection port by the 1st the 2nd above-mentioned spigot surface Ga, Gb in sheet material rear end Have no time after 29a to make sheet material rear end fall the function processed on pallet the most forcibly, and swimmingly after sheet material End is directed to be grilled into the function of roller 38.
Above-mentioned 1st spigot surface Ga be arranged in along the direction of ADF path line PL be held in standby attitude Fa kick to send parts On 50.And, the 2nd spigot surface Gb, to be gathered in the uppermost sheet material processed on pallet and from row when movement posture Fc The angle (diagram β angle) tilted between the sheet material rear end that paper mouth 29a falls is constituted.
The fan shape that 2nd spigot surface Gb of diagram has been formed to be curved.Rearward end 50b at swing arm parts 50 sets Have carry out with displacement member 52 described later engaging by dynamic holding section 50c, in figure, be made up of the tongue piece of tabular.
To above-mentioned kicking to send parts 50, exit roller 31, the position relationship of twist rollers 36 illustrate.
Exit roller 31 and twist rollers 36, as illustrate before, are configured in shorter than the conveying direction length of sheet material Position.Roller interval L shown in Fig. 4 is configured to shorter than the conveying direction length of minimum dimension sheet material.
Thus, the sheet material carried from ejection port 29a is formed by both sides' clamping of exit roller 31 and twist rollers 36 State.
The above-mentioned parts 50 that kick to send are arranged between exit roller 31 and twist rollers 36, are configured to so that its weight be applied to by It is clamped in engaging attitude Fb that the above mode of the sheet material between two rollers carries out engaging.This engaging attitude Fb is set at above-mentioned treating Between machine attitude Fa and movement posture Fc (Fig. 4 Fb: chain-dotted line state).
When this engaging attitude Fb, sheet material acts on the chucking power of exit roller 31, kicks to send the weight of parts 50, twist rollers The chucking power of 36, is moved towards ADF direction by the carrying capacity of exit roller 31 with twist rollers 36.Now when the weight kicking to send parts 50 When acting in the way of processing on pallet to make sheet material fall to, conveying can be caused bad.
Then, with chucking power (roll-in × coefficient of friction) and the chucking power (roll-in × friction of twist rollers 36 of exit roller 31 Coefficient) compare, the weight (quality × gravity) kicking to send parts 50 is set smaller than both exit roller 31 and twist rollers 36 Chucking power.
And the circular velocity of twist rollers 36 is set to be greater than the circular velocity of exit roller 31, meanwhile, twist rollers 36 to sheet The pressure of material effect is set smaller than the exit roller 31 pressure to sheet material effect.
Under the relation of such power, the sheet material sent from ejection port 29a is limited by the circular velocity of exit roller 31, turns over Transfer roller 36 is stretched sheet material front end and is carried out conveying of sliding.And kick to send parts 50 and made sheet material bend by unlikely under the relation of this power The weight of the degree of (relaxing) is constituted.
(structure of displacement member)
The displacement structure that parts 50 move back and forth between standby attitude Fa and movement posture Fc is kicked to send to above-mentioned The structure of part 52 illustrates.Fig. 5 (a) represents makes above-mentioned swing arm parts 50 by cam mechanism in position of readiness Fa and action The embodiment, same to figure (b) expression that move back and forth between the Fc of position make swing arm parts 50 back and forth be transported by linkage Dynamic embodiment, same to figure (c) represent the embodiment making swing arm parts 50 be moved back and forth by gear mechanism.
Cam mechanism shown in Fig. 5 (a), is provided with cam snap-latch piece 53 at the radicle 50x of swing arm parts, this cam card Close sheet 53 and be formed the shape of diagram as inverted cam.It is configured with rotation in the position carrying out engaging with this cam snap-latch piece 53 Rotating cam 55.The rotation cam 55 of diagram can be supported on device framework by the way of rotating, has fan shape by fulcrum Cam surface.
The above-mentioned actuating motor M2(that ins succession on this rotation cam 55 is also used as making twist rollers carry out the actuating motor lifted, But independent motor can also be used to make cam rotate), it is configured to, it is possible to not shown position sensor and sensor flag Mark detects rotary angle position.Above-mentioned actuating motor M2 is by the rotating horse carrying out oscillating motion with angle, θ set in advance Reach composition, driving is delivered to axle branch 36x and rotates cam 55.
And rotate cam 55 and be controlled so as to be still in holding position Hp and the diagram dotted line position of diagram solid line position Holding fix Up(with reference to control member described later).
When rotating cam 55 and being in holding position Hp, kick to send parts 50 and be positioned in standby attitude Fa, when rotating cam 55 when being in holding fix Up, kicks to send parts 50 unfettered and be in engaging attitude Fb or movement posture Fc.
Attitude holding cam surface 55a and displacement cam surface 55b it is formed with on cam 55 rotating.Above-mentioned attitude keeps cam Face 55a is maintained at standby attitude Fa at the holding position Hp carrying out engaging with cam snap-latch piece 53 swing arm parts 50.
And at the holding fix Up that have rotated toward the clockwise direction with diagram θ angle from this holding position Hp, cam surface 55a and cam snap-latch piece 53 become non-engagement state.
And when counterclockwise rotating θ angle from holding fix Up towards diagram, displacement cam surface 55b makes cam engage Sheet 53 rotates predetermined angular and shifts into the state of the solid line in this figure.So, make to kick to send parts rotating to possess on cam 55 50 are displaced to engage the action of attitude Fb from standby attitude Fa, and make to be positioned at operating position Fc kick to send parts 50(with figure dotted line State) it is displaced to the action of standby attitude Fa, when kicking to send parts 50 and being in engaging attitude Fb, the angle being formed with rotating cam 55 The non-engagement state that degree position independently freely swings.
The displacement member of Fig. 5 (b) is illustrated.Constitute identically with embodiment before and kick to send parts 50, formed Axle branch 36x and cam holding section 50c.
It is in and 50c position in opposite directions, this cam holding section can be arranged on by the way of rotating by 56 actuating struts 54 of axle On device framework.This actuating strut 54, to make radicle 54a can be supported on device framework in the way of axle 56 rotation, is configured to Leading section 54b is made to engage with cam holding section 50c.
Under diagram state, when turning around when making actuating strut 54 counterclockwise revolve, cam holding section 50c is from dotted line shape State rotates the angle of predetermined angular β in the direction of the clock towards solid line state.Then, it is provided integrally with this cam holding section 50c's Kick to send parts 50, be displaced to standby attitude Fa from movement posture Fc.Axle 56 at actuating strut 54 is ined succession not shown shifting motor M5(such as impulse motor).
When by and also time impulse motor makes actuating strut 54 rotate predetermined angular, kick to send parts 50 from standby attitude Fa displacement To non-engagement attitude, then it is displaced to movement posture Fc(dashed lines states).
It addition, the shifting motor of actuating strut 54 is configured to, make actuating strut by not shown position sensor and flag 54 rotate between the holding position Hp and the holding fix Up of dotted line of Fig. 5 (b) solid line.
And control device described later is configured to, make actuating strut 54 counterclockwise rotate towards diagram and in holding position Hp temporarily ceases with holding fix Up, and the time corresponding to ADF action starts to rotate from these stop positions.
Therefore actuating strut 54 is maintained at standby attitude Fa at holding position Hp kicking to send parts 50, is rotating to holding fix The period of Up, make to kick to send parts 50 and be positioned at engaging attitude Fb.And when rotating to holding position Hp from holding fix Up, make to play Parts 50 are sent to be displaced to standby attitude Fa from movement posture Fc.
The displacement member of Fig. 5 (c) is illustrated.Formation axle on parts 50 is being kicked to send in the same manner as above-mentioned displacement member 52 Branch 36x.On this axle branch 36x with kick to send parts 50 and form driven gear 57.
The teeth-missing gear 58 engaged with this driven gear 57 is pivotally supported on device framework, by not shown displacement Motor M6 rotates.
